Updated Spawn

Some really good news from over at DIYAudio: Spawn Olson/Nagaoka Horns the Next Generation

These are modern backloaded horns, designed with modern simulation tools and applying best-practice of decades of horn design. They were existing designs, but are adjusted to suit more recent Fostex fullrange drivers. The care invested in these horns is admirable and the updating shows a commitment to quality beyond the first act of creation. There are several build reports online (for instance here) and reviews of soundquality these designs are very good. It is good to see these designs available freely (for non-commercial use only, contact the designers first before any commercial activities).
